PRO Refrigeration introduces the PROGreen50, a compact, high-efficiency COâ‚‚ chiller for dairies, food producers, and craft beverage makers. The system expands the PROGreen Solutions initiative with a smaller, affordable, heat-reclaiming solution that reduces synthetic refrigerant use. The first PROGreen50 will be installed at Hanabi Lager Company in Napa Valley, helping pioneer COâ‚‚-based refrigeration in craft brewing. Key partners include Future Green Now, Dorin Compressor, and Thermal Supply Inc. PRO invites dealers, suppliers, and sustainability advocates to join the PROGreen Team and shape the future of natural refrigeration technology.
AUBURN, Wash., July 10, 2025 /PRNewswire-PRWeb/ -- PROChiller Systems proudly announces the official launch of the PROGreen50, a next-generation CO₂-based chiller designed for North America's top dairies, food producers, and craft beverage makers. This marks a pivotal expansion of the company's PROGreen Solutions initiative—first introduced with the pioneering PROGreen100 systems now in operation at seven California dairies and a craft distillery in Alaska.
Building on the success of the PROGreen100, the PROGreen50 introduces a compact, highly efficient design suited for smaller operations. It delivers superior cooling performance while reclaiming waste heat, making it an ideal fit for applications demanding both chilling and hot water—such as those in dairy farming and craft brewing.
Strengthened by Industry-Leading Partners
The PROGreen50 launch is further bolstered by key industry partners who bring unmatched expertise and technology to the project. Future Green Now will return and serve as a refrigeration engineering partner, continuing what began five years ago with the first PROGreen system. "This is an exciting project. The goals have changed; this time, more focus is on efficiency and affordability," Wynand Groenwald, CEO at FGN, adding, "Both teams have learned so much, huge benefit to apply that directly into this new system."
Additionally, Dorin Compressor has joined as an early supply partner. "We are honored to support PRO as a supplier partner on this important project, helping to explore and develop CO2 solutions — more common among our European customers — that maximize efficiencies and performance," said Giacomo Pisano, head of CO2 Compressors Business Development for Dorin.
Another strategic partner includes Thermal Supply Inc., a leading NW-focused Refrigeration Wholesaler, providing PRO's team access to training facilities and providing some great discounts to purchase critical tools that today's service technicians need to support this new technology.
These partnerships underscore the commitment to delivering a durable, efficient, serviceable, and affordable chiller solution targeting GWP 1.
"The PROGreen50 represents our boldest step forward in sustainable refrigeration," said Jim VanderGiessen, CEO of PRO Refrigeration. "This system is about doing more with less—smaller footprint, sharper efficiency, and a real-world solution to reducing synthetic refrigerant use. We are also focused on providing an affordable solution with a solid ROI."
A Call to Collaborate
To bring this solution to market, PRO is building a PROGreen Team, made up of customers, colleagues, engineers, dealers, suppliers, contractors, industry experts, and more. Participants collaborate on system development, field testing, storytelling, and customer education, helping to fine-tune the technology and maximize its impact.
At the core, the PROGreen50 will be more than a process chiller system using CO2 as a refrigerant— it will set the bar high for the competition on efficiency, durability, serviceability, and return on investment.
Key system features include:
- Dual compressor system with variable frequency drives
- Air-cooled gas cooler with adiabatic features
- PROHeat2o dual-loop heat recovery
- 400-gallon glycol reservoir and dual-process pumps
- Factory and field training, remote monitoring, and full commissioning
- Three-year full warranty and support plan
Nick Gislason, acclaimed winemaker, brewer, and founder of Hanabi Lager Company, will host the first PROGreen50 system at his brewery in Napa Valley. "We're honored to pioneer this technology," said Gislason. "I see huge potential for COâ‚‚-based refrigeration in industries that haven't considered it seriously. I hope we can prove the performance and sustainability benefits and open the door for more wineries and breweries to adopt this game-changing solution."
